Urinary Sebacic Acid (Sebacate)
Ten-carbon dicarboxylic acid produced by omega-oxidation of decanoic acid during severe mitochondrial fatty acid oxidation failure.
Standard vs. Optimal Reference Rangesug/mg Cr
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<0.5 ug/mg Cr
General reference distribution across unselected commercial populations.
<0.2 ug/mg Cr
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Excreted alongside adipate and suberate during active dicarboxylic aciduria when mitochondrial carnitine shuttles are exhausted.
Differential Diagnosis
Elevated Levels (Sebacate High)
- •Long-chain fatty acid beta-oxidation disorders (VLCAD, LCHAD)
- •Severe fasting metabolic decompensation
- •Carnitine depletion
Low Levels (Sebacate Low)
- •Quiescent, efficient mitochondrial beta-oxidation
- •Intact acylcarnitine shuttle

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker quantification for Sebacate
- Targeted organ system imaging or functional dynamic testing related to long-chain dicarboxylic acid spillover
- Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
